LibDoc 4.4.0.0-b.27 The content file SysReadWriteLock.clean.json was generated with CODESYS V3.5 SP16 Patch 3 on 20.04.2021, 16:06:53.

SysRWLDelete (FUN) ¶ FUNCTION SysRWLDelete : RTS_IEC_RESULT This function can be used to delete a ReadWrite locking object (synchronization object) RETURN: Returns the runtime system error code (see CmpErrors.library) InOut: Scope Name Type Comment Return SysRWLDelete RTS_IEC_RESULT Input hRWLock RTS_IEC_HANDLE Handle to the ReadWrite lock object created by SysRWLCreate

SysRWLCreate (FUN) ¶ FUNCTION SysRWLCreate : RTS_IEC_HANDLE This function can be used to create a ReadWrite locking object (synchronization object) RETURN: Handle to the semaphore or RTS_INVALID_HANDLE if failed InOut: Scope Name Type Comment Return SysRWLCreate RTS_IEC_HANDLE Input pResult POINTER TO RTS_IEC_RESULT Pointer to runtime system error code (see CmpErrors.library)

SysRWLReadLock (FUN) ¶ FUNCTION SysRWLReadLock : RTS_IEC_RESULT This function to enter a read lock(synchronization object). NOTE: Several readers can enter the lock simultaneously! But they are synchronized against an entered write lock! RETURN: Returns the runtime system error code (see CmpErrors.library) InOut: Scope Name Type Comment Return SysRWLReadLock RTS_IEC_RESULT Input hRWLock RTS_IEC_HANDLE Handle to the ReadWrite lock object created by SysRWLCreate

SysRWLReadLockTry (FUN) ¶ FUNCTION SysRWLReadLockTry : RTS_IEC_RESULT This function tries enter a read lock(synchronization object). If a write lock is still active, the functions returns an error. The function succeeded as well, if another read lock is still active. NOTE: Several readers can enter the lock simultaneously! But they are synchronized against an entered write lock! RETURN: Returns the runtime system error code (see CmpErrors.library) InOut: Scope Name Type Comment Return SysRWLReadLockTry RTS_IEC_RESULT Input hRWLock RTS_IEC_HANDLE Handle to the ReadWrite lock object created by SysRWLCreate

SysRWLReadUnlock (FUN) ¶ FUNCTION SysRWLReadUnlock : RTS_IEC_RESULT This function leaves a read lock, entered by SysRWLReadLock (synchronization object). RETURN: Returns the runtime system error code (see CmpErrors.library) InOut: Scope Name Type Comment Return SysRWLReadUnlock RTS_IEC_RESULT Input hRWLock RTS_IEC_HANDLE Handle to the ReadWrite lock object created by SysRWLCreate

SysRWLWriteLock (FUN) ¶ FUNCTION SysRWLWriteLock : RTS_IEC_RESULT This function to enter a write lock(synchronization object). NOTE: Several readers can enter the lock simultaneously! But they are synchronized against an entered write lock! RETURN: Returns the runtime system error code (see CmpErrors.library) InOut: Scope Name Type Comment Return SysRWLWriteLock RTS_IEC_RESULT Input hRWLock RTS_IEC_HANDLE Handle to the ReadWrite lock object created by SysRWLCreate

SysRWLWriteLockTry (FUN) ¶ FUNCTION SysRWLWriteLockTry : RTS_IEC_RESULT This function tries enter a write lock(synchronization object). If a write lock is still active, the functions returns an error. NOTE: Several readers can enter the lock simultaneously! But they are synchronized against an entered write lock! RETURN: Returns the runtime system error code (see CmpErrors.library) InOut: Scope Name Type Comment Return SysRWLWriteLockTry RTS_IEC_RESULT Input hRWLock RTS_IEC_HANDLE Handle to the ReadWrite lock object created by SysRWLCreate
